AJAZZ AK820 Mechanical Keyboard 2026: How to Choose the Right QWERTZ Layout, Hot-Swap Features and Compact 75% Design

A compact mechanical keyboard should save space on a German desk, respond precisely while typing and still provide enough function keys for gaming. The AJAZZ AK820 mechanical keyboard combines a German QWERTZ layout with 82 keys, RGB lighting, hot-swap sockets, a gasket-mount design, USB-C connectivity and a volume control knob.

However, it is worth taking a close look at the specific variant before buying. Keyboards with similar model names may differ in layout, lighting, switches and connectivity.

Common Buying Challenges with Compact Mechanical Keyboards

1. “75%” Does Not Automatically Mean a German Layout

A 75% gaming keyboard typically includes a function row, arrow keys and several navigation keys. Even so, it may be offered with either a US QWERTY or German QWERTZ layout. For users in Germany, the positions of Y and Z as well as special characters are particularly important.

Before buying, check the following:

  • Is QWERTZ or “German Layout” explicitly stated?
  • Are German special characters such as Ä, Ö and Ü included?
  • Does the Enter key use the ISO format?
  • Do the product images match the technical description?

The AJAZZ AK820 variant described here is offered with a German QWERTZ layout and 82 keys. Another AK820 version in the range, however, features a US QWERTY layout. The model name alone is therefore not enough to identify the correct version.

2. RGB Lighting Says Little About the Actual Feature Set

“RGB” may refer to individually configurable per-key lighting, zone-based illumination or several preset effects. The claim of “1.6 million colours” should also be considered in conjunction with the available controls. Anyone wanting to customise the lighting via software should check whether compatible software is specified.

The AJAZZ AK820 is listed with several lighting effects, brightness levels and adjustable effect speed. However, individual product variants may differ between RGB and white backlighting. The specific product page should therefore be treated as the decisive source before placing an order.

3. Hot-Swap Does Not Mean Unlimited Compatibility

A hot-swappable keyboard allows mechanical switches to be replaced without soldering. What matters, however, is which sockets are supported. The QWERTZ AK820 is listed as compatible with 3-pin switches, while other AK820 variants specify compatibility with both 3-pin and 5-pin switches.

When replacing switches, users should:

  • disconnect the keyboard from the USB port,
  • use only compatible switches,
  • never force bent pins into the socket,
  • pull the switch straight upwards or insert it vertically.

Hot-swap functionality makes maintenance and customisation easier, but it does not eliminate the need to check pin compatibility.

Key Technical Criteria to Consider Before Buying

Layout and Dimensions

A compact 75% mechanical keyboard is smaller than a full-size model while retaining important keys for office work and gaming. According to the product specifications, the AJAZZ AK820 measures approximately 327 × 136 × 40 millimetres and weighs around 0.8 kilograms.

This leaves more room for a mouse but does not provide a dedicated number pad. Anyone who regularly works with spreadsheets, long columns of figures or accounting software may find a 96% or 100% keyboard more practical.

Switches and Typing Feel

The AK820 is described as featuring linear Sea-Salt switches. Linear switches have no tactile bump and are often preferred for fast input. Whether the sound is pleasing also depends on the keycaps, case, mounting system and acoustic dampening.

The integrated gasket-mount keyboard uses an elastic mounting system. Combined with multi-layer sound and vibration dampening, this can create a softer typing feel. A gasket-mount construction, however, is not an objective guarantee of a specific volume level or sound profile.

Connectivity and Media Controls

The AJAZZ AK820 is a USB-C keyboard with a detachable cable and wired connectivity. This means:

  • no battery charging,
  • no Bluetooth pairing,
  • no wireless connection,
  • direct media control via the rotary knob.

According to the description, the metal knob adjusts the volume and can mute the keyboard when pressed. For users who switch between workspaces or use tablets, a tri-mode keyboard with Bluetooth and 2.4 GHz wireless connectivity offers greater flexibility. For a fixed PC workstation, USB-C is the more straightforward option.
